ToaZZ-wlwmit may camera ti l i l I .Be it: known-that I, WILBIAM L. MARTIN,

l-larvard in the county of McHenry and State of Illinois, have invented certainunew and I useful Improvements; in Automatic which the following is a specification.

The invention relates to improvements in y A automatic watering. bowls or drinking foun- One of the objects of the inventionwis to provideanimproved wateringbowl for supplying drinking water tostock and more particularly toimil'ch cows. 1

Another object "is to provide anautomatic means for maintaining at:allgtirnes an adequate supply of dninking water in the bowl,

.for' fount, whichis notwwithin thecontrol of and cannot,berinterfered, with in'any manner'by' the animals thathdrink therefroim; 1 1 .Anoth'er object is the provisionwof means Anotherobjectisithe provision ofmeans for disconnecting. the bowl from the supporting frame "conveniently to, clean or empty the bow-1.1;,

iAnotherl-object is to provideimproved means whereby the bowl and-its appurtenances arev conveniently supported by the water supply pipe. 1 1

" both of its side edges whereby to -selectively swing it into inverted positionto empty and lclean it. 1 1

Another object isPto hinge thebowl at Other, further and more specifio-objects of the invention will become readily apparent to persons skilled in the art, from a consideration of the following description, .whentakenin conjunction with the drawi'ngs,wherein?-'- .1 iFigure' 1 is a central; longitudinal section taken on-ihn'e 1-1 of Fig. 1

The-bowl proper 5, as shown, is U-shape in-cross section having closed ends 6 and 7..- Its upperlongitildinal edges are turned outwardly into scrolls-or hollow cylinders,

8 and 9, to receivesupporting rods 10 and ,11, respectively i supporting fra1ne,.for supporting the bowl- 5, consistsof two horizontal members 12, and13,preferably in the shape of flat bars, joinedtogether atone end and turned upwardly; asat 14, into a plane substantially at right angles to the horizontal plane, and provided vwith a clip 15 on theupturned end for connection with a water supply pipe 16, by which the frame and bowl are supported. The clip is held to the bars 12 and--13,at the end 14, by means of bolts 17 that take through the clip and through the bar. 1

Near the end of the horizontal members through the outerends of the rods 10 and 111, respectively; The pins hold the rods n place and prevent their displacement.

jIb hELS heretofore been'explained that the rods 10" and ll-pass through the cylindri- -calterminal edges of thebowl 5, forthe purpose of holding thebowl in place. In the event that it shouldbe desirable to empty the bowl of its contents and for the purpose of cleaning it, either one of the rods 10or 11 may be pulled out of its place and the bowl may be made toswing clear and freely upon the other rod into inverted position; the re- 1 mainingrod serving as a pintle upon which the-bowl turns. I I

t lilnstead of making the frame members -12 andl-3 of one piece joinedby an integral yoke 14,;the yoke may be made of a separate piece and joined to. the horizontal frame .members 12 and 13;- by bolts23.

On the endfof the water supply pipe 16 ,is a nozzle 24, serving as a port and closed by a valve'25, wh1ch isypreferably, a part of'a plunger 26 that'is reciprocable within tl ecylinder 27 The cylinder is a part of ;th'evalve-housing 28. in the lower end of which is screwed a water feed pipe 29 which iextends to the bottom of the bowl and through which water comes from the supply pipe 16 into the bowl.

The object of placing the discharge end of the pipe at the bottom of the bowl is to prevent splashing of water when it is fed into the bowl. The splash of the water has a tendency to frighten the animals, but when the water is fed into the bowl from near the bottom, there is no splash.

The piston 26 is provided with a slot 30 that extends diametrically thereof and into which projects a short lever 31, pivoted as at 32. Two longer levers 33 and 34 are connected to the shorter lever 31 and extend forwardly and are connected to each end of the float 32] The levers, 33 and 34, are located under the side members 12 and 13, respectively, of the supporting frame, so that they are protected by the respective side members and are inaccessible by the stock, or animals that drink from the bowl. The object' of making two side levers 33 and 34 is to connect them to each end of the float and to be able to protect them by the frame. The levers 33 and 34 are connected to the float 32, as at 35 and 36, respectively.

A'protecting housing 37 is placed over the float to protect and guard it against interference by the animals and consists of a trough-shape housing, similar in character to that of the bowl, having on opposite edges cylindrical formations 38 and 39, similar to the cylindrical terminations 8 and 9 of the bowl. Rods 40 and 41 pass through the cylindrical portions 38 and 39 of the housing 37 and into hollow lugs, or eyes 42, that are secured to the frame members 12 and 13. If it is desired to get at the float 32 for any purpose, one of the rods 40 or 41, may be pulled out of its position and the housing 37 may be rotated upon the other rod, as in the case with the bowl, as heretofore described.

A; vertical wall 44 may be secured to either of the frame members 12 and 13, by means of clips 41-5. It is a means by which adjacent animals are prevented from drinking out of the bowl provided for a particular animal and. to prevent the particular animal from drinking from the bowl of the adjacent animal.

When it is desired to shut off the water supply, by closing the nozzle 24;, in order that it may not be affected by the operation of the float 32, a latch 47 is pivoted, as at 418, to the cylinder 27 and when thrown forward, as shown in dotted line position in Fig. 1, it holds the piston 26, so that its valved end is in contact with the end of the nozzle and retains the valve closed; at the same time'it retains the float 32 in its most upward position within the housing 37 Having described'my invention what I claim as new and desire to secure by Letters Patent is 1. A device of the character described having in combination a bowl provided with hollow, cylindrical, longitudinal edges; a supporting frame for said bowl having perforate lugs or eyes, depending therefrom spaced apart to admit the cylindrical edges and rods passing through the cylinders and respective eyes to hold the bowl in place.

2. A device of the character described having in combination a frame providing two, parallel, horizontal side members extending upwardly near their point of juncture; means to connect the upwardly extending part to a water supply pipe; spaced apart eye pieces extending downwardly. one near each end of the horizontal part of each frame member; a bowl having its side edges terminating in hollow cylinders; a rod passing through both eyes of a side member and the respective cylinder of the bowl, one on each side, and means to hold the rods in place.

. 3. A device of the character described comprising a bowl; a frame having side members to support the bowl; a valve in one end of the bowl; a float in the other end of the bowl; a pivoted lever connected to the valve and having two parallel lever members connected to the respective ends of the float, said levers located in the bowl immediately below the side members of the frame.

4. A device of the character described comprising a bowl; a frame having side members to support the bowl; a valve in one end of the bowl; a float in the other end of the bowl; :1 pivoted lever having its shorter end engaging the valve, the longer end being bifurcated and extending under the respective frame members to the bowl connected to the respective ends of the float and a protective housing extending over the top of the float.

5. A watering bowl device comprising a semi-cylindrical bowl closed at each end and having hollow cylindrical side edges; a su porting frame, having two a'ra-llel Sid; members respectively above said cylindrical edges; perforate lugs depending from said side members, spaced apart to admit the respective cylindrical edges of the bowl between each pair; a rod passing through two said lugs and the cylindrical edge of the bowl, on each side thereof; a valve to admit water, at one end of the how]; a float at the other end of the bowl; means connecting the valve and float; a semi-cylindrical housing having cylindrical side edges transversely positioned above said frame and overlying the float; perforate lugs extending upwardly from the frame members and a rod passing through each pair of perforate lugs and the respective cylindrical edge of: the housing on each side thereof.

6. A watering bowl structure comprising a frame having two parallel. side members; a bowl selectively hinged to either side frame member so that the bowl may be swung to inverted position from either side;

a valve in one end of the bowl to admit water; a float in the other end of the bowl; means conneotingthe said valve andfloat and means to hold the float elevated to close frame member so thatythe bowl .may be swung to inverted position from either side;

a valve in one end of the bowl to admit water in the bowl comprising a nozzle and a plunger; a float in the other end of the bowl arranged to move the plunger valve outwardly to open the nozzle when the water level is low and means to hold the valve on the end of the nozzle when the bowl is inverted.

;In testimony whereof I hereunto subscribe my name.
